Understanding Object-Oriented Programming in Java: A Beginner’s Guide

Object-Oriented Programming (OOP) is a paradigm that has revolutionized software development, and Java is one of the most popular languages that fully embraces it. In this article, we’ll explore the fundamental concepts of OOP in Java using simple examples and code snippets to make it accessible to beginners.

What is Object-Oriented Programming?

At its core, Object-Oriented Programming is a programming paradigm that models real-world entities as objects, allowing you to structure your code around these objects to represent and manipulate data. These objects have attributes (data) and methods (functions) associated with them, making it a powerful way to organize and manage complex systems.

Classes and Objects

In Java, everything revolves around classes and objects. A class is a blueprint for creating objects, defining their structure and behavior. An object, on the other hand, is an instance of a class, representing a specific instance of that blueprint.

Creating a Class

Let’s start with a simple example. Suppose we want to model a Person in our Java program. We can create a Person class:

public class Person {
    // Attributes…
